1940. They had four children in all, called the "million dollar babies" due to the amount of income the couple lost while Yolanda was pregnant and then nursing a newborn. Two of these children died in their twenties. In 1938, Veloz and Yolanda published a dance manual, Tango and Rumba: The Dances of Today and Tomorrow (New York: Harper & Brothers), co-written with Willard Hall. They hosted a TV show, The Veloz and Yolanda Hour, for several years. They opened a nightclub in Florida, The Iris. From the 1940s, the Veloz and Yolanda Dance Studios gave lessons in ballroom dancing for twelve hours each day, with the slogan "Walk In – Dance Out". The studios taught the Rhumba, Waltz, Fox Trot, Smooth Swing, Tango, Samba and Mambo. With each style, the student had to learn a series of steps or combinations. They would progress through the grades of "ruby" and "emerald" to the ultimate "diamond" level. In 1949, when Yolanda was pregnant, Frank Veloz danced with Jean Davi (born Jean Phelps) on the first Academy of Television Arts & Sciences awards. Jean was a Hollywood Lindy dancer who trained in ballroom dancing at one of the Veloz and Yolanda dance schools. After Yolanda retired, Jean became Frank's partner in stage and TV performances. When the fashion for ballroom dancing declined, replaced by new forms of dance, the Veloz and Yolanda schools began to close. The marriage broke up in the mid-1950s. In 1956, Yolanda sued Veloz for maintenance, accusing him of infidelity with Jean Davi, his dancing partner. The suit was dismissed the next year. In 1962, Veloz sued for divorce on the basis of extreme cruelty by his wife. Yolanda was to have custody of their minor children. Their children were Nicholas, 21; Anthony, 18; Yolanda, 16 and Guy, 12. Frank Veloz died in 1981. Yolanda Casazza died in 1995. A full-length ballet written by their son Guy Veloz, An American Tango, is based on their life story. Style and influence Veloz and Yolanda did much to legitimize ballroom dance as a performance art. Veloz and Yolanda were interested in the way animals moved about and were said to have studied horses to learn change of stride and tempo. They created the "Cobra Tango", a dance that interpreted a fight between a snake and a tiger. Veloz and Yolanda were known in particular for their interpretations of Latin Dance.
